Faux = false or fake. '
mo' is short for "homo(sexual)". Therefore "feaux 'mo' fashion show" means a
man wearing clothes that might cause him to appear gay, even though he is not. Such as when a
man accidentally (or purposely, for lack of clean clothes) wears an item of his wife'
s or girlfriend's clothing, not something as overtly feminine as a dress, but, say, some women's jeans, or a shirt that almost, but not quite, looks like a
man's shirt.
THOMPSON: Look at the "feaux '
mo' fashion show". It looks
like Jeff is accidentally wearing Sarah's CHIC jeans again!
